材料分析题:
材料一:《达尔文的悲剧》
达尔文是19世纪伟大的生物学家,也是进化论的奠基人。然而在他还没有掌握大自然中生物界的奥秘之前,自己先受到了自然规律的无情惩罚。 1839年,30岁的达尔文与他的表妹爱玛结婚。爱玛是他舅舅的女儿。他们两人从小青梅竹马,感情深厚。但是,谁也没有料到,他们的6个孩子中竟然有3个夭亡。这件事情让达尔文百思不得其解,因为他和爱玛都是健康人,生理上没有什么缺陷,精神也非常正常,为什么生下的孩子却都是如此呢?达尔文到了晚年,在研究植物的生物进化过程时发现,异花传粉的个体比自花传粉的个体,结出的果实又大又多,而且自花传粉的个体非常容易被大自然淘汰。这时,达尔文才恍然大悟:大自然讨厌近亲结婚。达尔文意识到自己婚姻的悲剧在于近亲,所以他把这个深刻的教训写进了自己的论文。
材料二:
科学家将男、女体细胞内的染色体进行分析整理,形成了下面的排序图。

请分析材料回答下列问题:
⑴材料一中,从达尔文婚姻的悲剧可以看出,____ 是预防遗传病发生的有效措施。
⑵达尔文体细胞染色体的组成是材料二中的____  图。
⑶若材料二中的排序图表示的是电视剧《鲜花朵朵》中七个女儿父母的染色体组成,假如他们再生一胎,是男孩的可能性为____ 。
⑷正常人的染色体数目是相对恒定的,这对生命活动的正常进行非常重要。如果人的体细胞中多了或少了一条染色体,可能导致严重的____ 。

    Ideas about polite behavior are different from one culture to another. Some societies, such as America and Australia, for example, are mobile and very open. People here change jobs and move houses quite often. As a result, they have a lot of relationships that often last only a short time, and they need to get to know people quickly. So it's normal to have friendly conversations with people that they have just met, and you can talk about things that other cultures would regard as personal.

    On the other hand, there are more crowded and less mobile societies where long–term relationships are more important. A Malaysian or Mexican business person, for example, will want to get to know you very well before he or she feels happy to start business. But when you do get to know each other, the relationship becomes much deeper than it would in a mobile society.

    To Americans, both Europeans and Asians seem cool and formal at first. On the other hand, as a passenger from a less mobile society puts it, it's no fun spending several hours next to a stranger who wants to tell you all about his or her life and asks you all sorts of questions that you don't want to answer.

    Cross-cultural differences aren't just a problem for travelers, but also for the flights that carry them. All flights want to provide the best service, but ideas about good service are different from place to place. This can be seen most clearly in the way that problems are dealt with.

    Some societies have “universalist” cultures. These societies strongly respect rules, and they treat every person and situation in basically the same way.

     “Particularist” societies, on the other hand, also have rules, but they are less important than the society's unwritten ideas about what is right or wrong for a particular situation or a particular person. So the normal rules are changed to fit the needs of the situation or the importance of the person.

    This difference can cause problems. A traveler from a particularist society, India, is checking in for a flight in Germany, a country which has a universalist culture. The Indian traveler has too much luggage, but he explains that he has been away from home for a long time and the suitcases are full of presents for his family. He expects that the check–in official will understand his problem and will change the rules for him. The check–in official explains that if he was allowed to have too much luggage, it wouldn't be fair to the other passengers. But the traveler thinks this is unfair, because the other passengers don't have his problem.
